time it is working, the second time the scanning does not start. The sc

Hi,
I have some severe issues with USB on a new system. This is
an Acer Aspire S5 (i7, Ivybridge) and the scanner can be mostly
classified as non working.
Symptoms:
1.) Start a scan application (e.g. simple-scan)
2.) Scan a page
3.) Exit the app
4.) Start a scan application (e.g. simple-scan)
5.)
